I'm going to give Bellagio 4 stars because the place really is pretty impressive. The restaurants are mostly top-notch, the rooms are nice (some much nicer than others), the hotel employees are helpful and polite, and having a cabana at the pool can be quite relaxing.
I just wish that this place had a dress code that is a little bit more strict. A tank top, shorts and flip flops might be great for Motel 6, but Bellagio? Seriously, people. Have a little class.
